Metabolic adaptation
Individuals with high skeletal muscle mitochondrial density (HI-CS) have higher VO(2)max and lower fasting respiratory quotient (RQ) compared to those with low mitochondrial density (LO-CS).
Higher mitochondrial density may enhance exercise capacity and metabolic efficiency in individuals.
StrongSupportsmedium confidence
HI-CS subjects had higher VO(2)max (50 ± 1 vs. 44 ± 2 ml/kg fat free mass/min; P = 0.01), lower fasting respiratory quotient (RQ) (0.81 ± 0.01 vs. 0.85 ± 0.01; P = 0.04).
Why this rating
Based on the comparison of physiological measures between groups.
